Oak Park Conservatory | Oak Park, Ill.

The exhibit, organized by the Purdue Agriculture Exhibit Design
Center, teaches children that mammals are carnivores, herbivores or
omnivores and that there are different types of teeth and feeding
habits for each. Among its features are animal skulls, including a
tiny weasel and a polar bear. Kids can look at their own teeth in
the Tooth Sleuth mirror to determine their eating category.
